They have been buy-able for a whilst, Libs and Labour just thought they had the upper handed monopoly and the candidates stopped 'looking' like they care in favor of the 'just rent and be glad you peasant'. This result is almost the same argument that is seen in USA and UK. Economics and class snobbery is hitting hard on the lower incomes, so social media is pushing the purchased self righteous, but useful idiots to make it even worse. Libs and Labour have helped create the mess, showing big money that they can buy public sway, the difference is that money is now sidestepping them playing dirty. They cant and wont object or offer resistance.
